Homemade hand warmers

These are basically beanbags, filled with rice. I stick them in the microwave for about 30 seconds before I leave, and put them in my mittens, on top of my fingers.

Plusses:

Keeps fingers toasty

Reusable (might have to replace rice periodically, don't know yet)

Minuses:

Only lasts about 15 minutes

Very damp heat

Only useable with mittens

A few years ago someone told us about making footwarmers by microwaving socks filled with rice, so we just adapted the idea. I thought I should share this in case anyone else wants to try it, or has any comments on having done something similar. I like that it doesn't use chemicals and that it is reusable. Maybe different material would produce a dryer heat. These are just terricloth from an old bathrobe I had just torn up into rags.
